Madeline (pronounced mad - eh - line) is so lovely and I love it's French charm. However, the overly-common nickname "Maddie" is absolutely atrocious and doesn't possess even 1% of the grace that the full name carries.
Seraphina is absolutely beautiful and ethereal. To see this magical name sawed down to a name as bland and overdone as "Sarah" just offends my ears.
Christopher. Such a strong name that blends in with the rest of the crowd when reduced to "Chris".
